CHARLES W. BENEDICT, OF ST. LOUIS, MISSOURI, ASSIGNOR OF ONE-HALF TO CHARLES J. JOHNSON, OF SAME PLACE.

PRESSURE-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 661,283, dated November 6, 1900.

Application tiled March 20, 1900. Serial No. 9,412. (No model.)

To all whom t may concern:

Beitknown that 1, CHARLES W. BENEDICT, a citizen of the United States, residing at St. Louis, State of Missouri, have invented new and useful Improvements in Pressure-Regulators, of which the following is a specification.

My invention relates to improvements in pressure-regulators; and it consists in the novel combination and arrangement of parts, as will be hereinafter more particularly described and claimed.

In the drawings, Figure 1 is avertical longitudinal section of my complete invention, showing the valve in an open position; and Fig. 2 is a similar section of the lower end of the pressure-regulator, showing the valve in a closed position.

The object of my invention is to construct a simple, practical, and durable pressureregulator, or one in which the air, gas, or other duid passing from the same for any purpose or service is automatically delivered at an even pressure notwithstanding the variable pressure of the liquid orfinid contained in a suitable reservoir to which the regulator is attached; and it consists in the specific construction of the device for accomplishing the above results, as hereinafter described.

Referring to the drawings, 1 represents a cylindrical chamber having a removable top 2, a diaphragm 3 being secured between the latter and the upper edge of said chamber, whereby the said diaphragm is securely held in position and secured to the medial portion of the diaphragm, and depending therefrom is a rod et, which passes freely through an en larged tubular extension 5, which is screwed into the bottom of the chamber 1 and depends therefrom, the upper end of said tubular eX- tension openinginto the interior of said chamber, and forming the lower end of the tubular extension is an enlarged portion 6, within which is formed a circular chamber 7, within which the air, gas, or other Huid first enters from the supply-pipe 8, leading from any suitable reservoir, the said pipe being screwed into a nipple 9, forminga continuation of the enlarged portion The chamber 7, formed in the enlarged portion (5 of the tubular extension 5, is in communication with the latter by a port 10, within which the reduced portion 11 of the rod 4 is located when the Valve is in an open position, whereby the Huid is free to pass through said port. The lower end 12 of the rod 4 is enlarged and is free to slide through an opening formed for its reception in the lower wall of the enlarged portion 6, but prevents the escape of any fluid, the lower end of the said rod or enlarged por- 6o tion 12 extending downwardlyasuitable distance beyond the enlarged portion (i of the tubular extension and being provided with screw-threads upon which is movable a nut 13, and encircling that portion of the rod and interposed between the nut 13 and the lower wall of the enlarged portion 6 of the tubular extension 5 is a coil-spring 14, whereby the proper amount of Huid and at a given pressure is accurately adjusted to be fed through 7o the pipe 15, connected to the chamber 1. By enlarging the lower end of the rod 4 an annular shoulder or seat 16 is formed, which is adapted to come in contact with the upper wall of the chamber 6 when the valve is in a 75 closed position, thereby entirely cutting oit the supply of iiuid to the chamber 1, the said result being accomplished, should the pressure of the fluid become excessive, by forcing the diaphragm 3 upwardly or in the position 8o as shown in dotted lines in Fig. 1, a slighter excessive pressure being overcome in the same manner by slight movement of the diaphragm, which would only partially close the valve.

Having fully described my invention, what I claim is- A pressure-regulator, comprising a suitable chamber, a diaphragm secured within t-he same, a supply-pipe leading from4 said cham- 9o ber, a tubular extension depending from the latter, and in communication with the same,

a chamber formed in the lower end of said extension, and in communication with said tubular extension by a suitable port, a sup- 95 ply-pipe leading from asuitable reservoir, attached to the lowerend of the tubular extenn sion, and in communication 'with the chamber formed therein, a rod attached to the said diaphragm and depending therefrom, and roo passing through the said tubular extension,

the lower end of said rod being enlarged and passing through the lower Wall of the extension, and projecting downwardly therefrom, said rod having a reduced portion passing through the port formedin the Cylindrical eX- tension, and a seat eoperating with the up between said nut and lower end of the eXtenro sion, as and for the purpose described.

In testimony whereof I affix my signature in presence of two Witnesses.

per wall of the chamber about said port, a CHARLES W' BENEDIC F' nut, screwed on the enlarged portion of the Witnesses:

stem, and a coil-spring encircling the en- C. J. ANDERSON, larged-porton of the stein, and interposed i C. F. KELLER.
